Musnad Ahmad 5:77

'Affan narrated to us, Shu'bah narrated to us, from 'Amr ibn Murrah, who said: I heard 'Abdullah ibn Salamah, from 'Ali, who said: I was complaining [of an ailment], and the Messenger of Allah (peace and blessings of Allah be upon him) passed by me. He mentioned its meaning, except that he said: "O Allah, grant him well-being; O Allah, heal him."
